Well, you seem to assume that morality requires some authority to implement it. I'm not sure I can see why. You certainly need it for the Law, but why for morality. I don't think slavery is wrong because I was told it was wrong, I think its wrong because its wrong.
I basically believe that, ultimately, morality is a product of our understanding of who we are and what we are, you don't need some big guy in the sky saying "these are the rules and if you don't obey them you are in deep do-do". In fact, I'm not really keen on the kind of view that morality involves a set of rules that require obedience. In other words if I was religious I'd take a lot more notice of the Sermon on the Mount than I would of the ten Commandments.
Of course, all of this depends on what you mean by "authority" (or, probably more precisely, what kind of "authority" you are talking about). There's a huge difference between the arbitrary "authority" of a dictator, the delegated "authority" of a representative and the "authority" someone may have because of their knowledge and presumed wisdom - and that's just for starters.
In the moral arena (as opposed to the legal arena) I can't see why we
need any of them, but of them only the third has any real relevance.
Ultimately, as I said morality comes from our intellect, our empathetic ability and our social existence. That gives us the potential for moral development. We are the ultimate arbiters. Morality, after all is about how we should live our lives.
That's a kind of similarity between my position and the belief in "natural and "inalienable" rights. We both believe that morality comes out our development as social animals. Its just that we have different stories about how that development occurred, and mine is a far more accurate story .....
